# Kites

Boys run kite on a cable of 68 meters long. What is the kite altitude, if the angle from the horizontal plane is 72°?

Result

h =  65 m

#### Solution:

$l = 68 \ m \ \\ \sin A = h:l \ \\ \ \\ h = l \cdot \ \sin( 72 \ \ ^\circ = 72 \cdot \ \dfrac{ \pi }{ 180 } \ rad = 64.6718431081 \ rad ) = 65 \ \text { m }$
